Title: Pwm system a/d converter
Inventor: YAMANE YASUNARI
IPC: H03M1/14
Filed: 1992-04-24
Abstract: PURPOSE:To provide a feed-back-type PWM system A/D converter where measurement is executed in a short time without changing a clock frequency or a circuit constant by newly providing a time transfer means and a feed-back signal change-over means. CONSTITUTION:The output of an integrator 4 at a first cyle becomes the output of a conventional PWM signal. But, a delay PWM signal synchronized with a clock pulse in the time transfer means 10 is inputted to a feed-back signal generating part 7 with the feed-back signal changeover means 15. Therefore, the rising of a feed-back signal ES(+ES, -ES) outputted from the feed-back signal generating part 7 deviates for the portion of its fraction time. Then, the deviation affects the deviation of integration time and, moreover, gives change to the PWM signal. For example, when the time width of pulse width DELTAt1 is comparatively long, the succeeding PWM signal becomes short and compensation for the portion of the deviation in the last time is executed. Thus, correlative relation between the cycles is generated so that the effect of i-time measurement comes to be statistically the same as the effect of i<2>-time measurement when the last fraction time of DELTAt1 and DELTAt2 is measured.

IPC: C08L63/00
Filed: 1990-04-23
Abstract: PURPOSE: To improve the electrical insulating property and thermal conductivity of an insulating metallic substrate and the adhesion of the substrate to a metallic film, by forming the substrate of a high density zone in which an alumina film has a specific thickness and uniform adhesion to aluminum and a porous layer having a rough external surface. CONSTITUTION: An insulating metallic substrate has an aluminum base layer, an insulator composed of an alumina film obtained by anodically oxidizing at least one surface of the base layer, and at least one metallic film which is constituted so that the film can be worked to a conductor circuit network by chemically etching. The substrate is constituted of a high-density zone in which the alumina film has a thickness of >500nm and uniform adhesion to aluminum and a porous layer having a rough external surface. When the thickness of the high-density zone is <500nm, the electrical insulating property of the metallic substrate becomes insufficient and, when the thickness becomes over 1,200nm, on the other hand, the thermal conductivity of the substrate becomes inappropriate.  Therefore, the thermal conductivity and electrical insulating property of the substrate and the adhesion of the substrate to a metallic film can be improved.
